Volume of the original sphere:
Volume = 4/3πr^3
Original sphere has a radius of 8 cm:
Volume = 4/3 * 3.14 * 8^3
Volume = 4/3 * 3.14 * 512
Volume = 2143.57 cubic cms.
Volume of smaller sphere with radius of 2 cm:
Volume = 4/3 * 3.14 * 2^3
Volume = 4/3 * 3.14 * 8
Volume = 33.49 cubic cms.
Number of balls that can be made: 2143.57 / 33.49 = 64
Answer:
The correct answer would be 2.4
Step-by-step explanation:
Step-by-step explanation:
There are 21 socks in total. Only 7 of them are white.
When you pick your 1st sock, you have a 7/21 chance to get white.
When you pick your 2nd sock, you have a 6/21 chance to get another white, since you already picked a white.
So the probability to get a pair of white socks is 2/21.
Answer:
60 degrees.
Step-by-step explanation:
We use trigonometry of a right angled triangle:
Adjacent side = 20 ft, Hypotenuse = 40 ft.
cos x = adjacent / hypotenuse = 20/40 = 1/2
x = 60 degrees.
